BURR-WHEEL.

SPECIFICATION forming part of Letters Patent No. l91,345, dated February 7', 1893. Application filed September 15, 1892. Serial No. 445,934. (No model.)

To all whom 'it may cow/cern.:

v Be it known that l, ROBERT W. GORMLY, a citizen ot the United States, residing at Troy, county of Rensselaer', and State of New York, -have invented certain new and useful linprovexnents in Burr-Wheels, of which the following is a specification.

lily invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference maybe had to the accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure l of the drawings is a vertical central section oi my improved burcwheel. Fig. 2 is a view in side elevation of the oil-cup, spindle and supporting bracket. Fig. 3 is a bottom plan view of the sleeve by which the body section of the wheel is rotatably secured to the oil-cup.

In illustrating my invention, l have shown a well known type of wheel in which the radial blades, A- are clamped upon a radially slotted bodysection, A- by a washer or cap, A2. The cap is secured tothe body-section by a bushing, ladapted to t a central aperture in the bodysection, and exteriorly threaded at its upper, or outer, end to fit` the interiorly threaded socket, Alin the cap. The lower or inner end of the bushing is provided exteriorly with an annular flange, A5- to bear upon the inner side ot' the body-section, or an intervening washer, A6-.

B is a spindle tired at its lower end in a supporting bracket, B--, as by set-screw, B2, and having its upper end adapted to enter and iit the bushing, s- When in use, the wheel is supported by, and rotates upon, the spindle in the position shown in Fig. l.

in someltinds of burr-wheels, such as clearing-wheels, it is necessary to provide rnechan ism for securing the rotary portion upon the supporting spindle. Heretofore, a screwthreaded bolt has been inserted through a central aperture in the cap into a threaded central aperture in the outer end of the spinn die, a head upon the outer end of the screw or bolt bearing upon the outer surface of the cap to hold the same upon the spindle. In such a form of construction, or any form which necessitates perforating the cap, the oil deposited in the cup, O- for the purpose of lubricating the spindle beaiings,\vould be forced up through the aperture in the cap and soil the yarn or knitted fabric.

My improved form of construction avoids the necessity for an aperture through the cap, and consists in securing the rotary part of the wheel, by a connection on its inner, or lower, side with the oil-cup. The cup incloses the spindle as shown, and is provided on one side with an open slot or recess, O adapted to receive the shank oi' a screw. The ring or sleeve, D- is adapted to receive and loosely iit the boss, AL- on the inner side of the bodysection, and is provided with an annular groove, D- adapted to receive and loosely it the edge wall around the mouth of the cup. The sleeve is also provided with a threaded aperture, opening outwardly, adapted to receive and tit the screw 32-, To secure the rotary parts to the spindle, the screw is inserted in the recess, C- and screwed into the threaded aperture in the sleeve D until the head of the screw bears upon the recess walls of the cup. The washer, A6@ will engage with the sleeve to prevent the rotary parts of the wheel from being detached from the spindle. Such parts can be easily detached for cleaning or repairs by a slight backward turn of the screw which will loosen its hold upon the cup and permit it to slide out of the open end of the recess. The rotary movements of the bushing draw the oil from the oil-cup and carry it to the upper end of the spindle, as required for use. lt is wholly confined and prevented from escaping from the spindle-socket by the closing cap.

I do not wish to be limited to the mechanism shown for connecting the rotary parts to the oil-cup, as any known mechanism maybe employed for that purpose. When desired the blades may be soldered to the body-section, or secured thereto in anyknown manner.

lVhat l claim as new and desire to secure by Letters Patent is l. The combination in a burr-wheel of a fixed spindle; a blade-supporting body-sec- IOO tion; a cap foi closing the outer end of the bushing; a sleeve rotatably secured to the body-section; and means for securing the Sleevetotheoileup,substantiallyasdescribed. 15

In testimony whereof I have hereunto set myhand this 10th day of September, 1892.

ROBERT W. GORMLY.
